TEMPORARY BINDER.

Application filed February 10, 1916.

To all whom it may concern:

Be it lmown that I, Gnonon P. VVIGGINTON, a citizen of the UnitedStates, residing at the city of Kalamazoo county of Kalamazoo, State ofMichigan, have invented certain new and useful Improvements in TemporaryBinders, of which the following is a specification.

This invention relates to improvements in temporary binders.

My present improvements are particularly designed by me for embodimentin binders of the type shown in Letters Patent No. 1,010,556, issued tome December 5, 1911, and are an adaptation and, in some respects, animprovement upon the structure there illustrated.

The main objects of this invention are:

First, to provide in a temporary binder or loose sheet holder animproved adjusting mechanism.

Second, to provide an improved temporary binder or loose sheet holderwhich is ca' pable of rapid manipulation to permit the removal orinsertion of the leaves and one in which the mechanism is compact andsimple.

Further objects and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a detail inside plan view of a structure embodying thefeatures of my invention.

Fig. 11' is an enlarged inverted detail of the adjusting mechanism.

Fig. HT is a side view of the adjusting key.

Fig. V is a detail inside plan view of a modified form of my invention.

Fig. V1 is a detail inside view of the adjusting mechanism of theembodiment shown in Fig. V.

In the drawing similar reference characters refer to similar partsthroughout the several views.

Referring to the drawing, the covers 1 and 2 are of any suitablestructure, the cover 2 Specification of Letters Patent.

being provided with a chamber or recess 3 for the adjusting mechanism.The binding members 4L are preferably in the form of flexible strips andextend between the covers, being connected to the cover 1 at 5 and tothe cover 2 through the adjusting mechamsm.

The adjusting member 6 for the binding members is slidably mounted uponthe rack bar 7 which is disposed longitudinally of the cover 2. Theseparts are in general the same as in my patent before referred to. Theadjusting member 6 is secured in its adjusted position upon the bar 7 bymeans of the pawl 8 pivotally mounted at 9 on the inner side of theadjusting member. This pawl is held yieldingly in its operative positionby means of the U-shaped spring 10, one arm of which is mounted on thepin 11 so that its free arm engages the pawl. The spring is alsoarranged so that it supports the pawl in inoperative position againstthe stop 12. See the dotted lines in Fig. 11. v

The pawl is shifted to and from its operative position by means of thekey 13 having a bit 14 adapted to engage between the tangs 15 on thepawl.

The adjusting member 6 is provided with a key opening 16 for the key 13.The key is provided with an arm 17 which rides upon the top of themember 6 supporting it for rotative movement in the opening 16.

The adjusting key 18 is provided with pinion teeth 19 adapted to coactwith the teeth of the bar. The adjusting member 6 has anopening 20adapted to receive the key 18 and support it with its teeth or pinion inrotative engagement with the rack so that the rack may be adjusted bymeans of the key, the key, in efl' ect, constituting an adjustingpinion.

The pawl, as stated, holds the parts in their adjusted position, butwhen released, as by means of the key, the adjusting member slidesfreely on the bar.

By this arrangement ofvparts, the binder may be quickly adjusted toextend or retract the binding members and when the binder is locked orthe binding members are under stress they cannot be released except bymeans of the key or its equivalent, which is efiective in preventingaccidental releasing of the same or ordinary unauthorized manipulation.

The key opening 16 may, if desired, be

1 llll sealed, so that the binder cannot be opened without its becomingknown.

In the modification shown in Figs. V and VI the binding strips areconnected to an adjusting member or cross bar 21 having a rack bar 22connected thereto. Ihis bar slides through the cross piece 28 mounted onthe cover.

The adjusting means and the means for retaining the parts in theiradjusted position Xarre the same as those described in Figs. II

I have not attempted to illustrate or describe certain othermodifications and adaptations of my improvements which might bedesirable for certain conditions or adaptations, as I believe thedisclosure made will enable those skilled in the art to which myinvention relates to embody or adapt the same as conditions or taste mayrequire.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is:

1. In a temporary binder, the combination of a binding member, a rackbar, an adjusting member for said binding member slidably mounted onsaid bar, a pawl mounted on the inner side of said adjusting member tocoact with said bar, a spring adapted to hold said pawl yieldingly inits operative and inoperative positions, a stop for said pawl when ininoperative position, and a key for adjusting said pawl to its operativeand inoperative positions, said adjusting member having an openingtherein for said key.

2. In a temporary binder, the combination of a binding member, a rackbar, an adjusting member for said binding member slidably mounted onsaid bar, a pawl mounted on the inner side of said adjusting member tocoact with said bar, a spring adapted to hold said pawl yieldingly inits operative and inoperative positions, and a key for adjusting saidpawl to its operative and inoperative positions, said adjusting memberhaving an openingtherein for said key. 3. In a temporary binder, thecombination of a binding member, a rack bar, an adjusting member forsaid binding mem ber slidably mounted on said bar, a pawl mounted on theinner side of said adjusting member to coact with said bar, a springadapted to hold said pawl yieldingly in its operative position, a keyfor adjusting said pawl to its operative and inoperative positions, saidadjusting member having an opening therein for said key, and anadjusting key provided with pinion teeth adapted to coact with the teethof said rack, said adjusting member being provided with an openingpositioned to supportsaid key in rotative engagement with said rack 4,In a temporary binder, the combination of a binding member, a rack bar,an adjusting member for said binding member slidably mounted on saidbar, a pawl for retaining said adjusting member in its adjustedpositions on said bar, mounted on the inner side of said adjustingmember, a removable key for releasing said pawl, and an adjusting keyprovided with pinion teeth adapted to coact with the teeth of said rack,said adjusting member being provided with an opening positioned tosupport said key in rotative engagement with said rack.
